Is it possible to take the train from Versailles to Chartres without having to double back to Paris? The French train website refuses to tell me, and the RailEurope website doesn't recognize "Versailles" as a valid starting point. (Based on these and past experiences, I firmly believe that all train websites hate me. But I'm not at all paranoid. Really.)
My tour group will be spending the morning at Versailles, and then I'd like to spend the rest of the day in Chartres if possible. If Versailles - Chartres is a valid route, does anyone know how long the journey is and approximately how much the second-class, adult fare is on a weekday afternoon?
